Analysis of Fretting Damage in Polymers by Means of Fretting Maps

The features of the fretting-wear behavior of glassy polymers against rigid counterfaces are reviewed through fretting maps concepts. The suitability of an elastic analysis to describe the fretting conditions in Running Condition Fretting Maps is discussed on the basis of numerical and experimental investigations of the contact zone kinematics. Material response in terms of cracking is subsequently analyzed in relation to the contact loading and to the plain fatigue properties of the polymer.
